The invention is applicable to the technical field of substations, and provides a bidirectional DC power control system and method for substations. The system includes: a bidirectional converter module, used to send a disconnection signal to the control module when the grid is powered off; The input sends an instruction to start the nuclear capacity mode to the two-way converter module; the two-way converter module starts the emergency power supply mode, and sends the first discharge command to the battery power supply module, or sends the second discharge command to the battery power supply module in the nuclear capacity mode; the battery power supply The module outputs the first direct current according to the first discharge command, or outputs the second direct current according to the second discharge command, and the bidirectional converter module records the power information of the second direct current. The invention can provide emergency power supply, reduce the investment of uninterruptible power supply equipment, and at the same time, can automatically carry out nuclear capacity on the battery module, reduce manual operation, and save material resources and manpower.
